Text improved and extended", "categories": [ "math.AP", "math.CT" ], "abstract": "We define here the category of partial differential equations. Special cases of morphisms from an object (equation) are symmetries of the equation and reductions of the equation by a symmetry groups, but there are many other morphisms. We are mostly interested in a subcategory that arises from second order parabolic equations on arbitrary manifolds. We introduce a certain structure in this category enabling us to find the simplest representative of every quotient object of the given object, and develop a special-purpose language for description and study of structures of this kind. An example that deals with nonlinear reaction-diffusion equation is discussed in more detail.", "revisions": [ { "version": "v5", "updated": "2009-05-29T09:04:07.000Z" } ], "analyses": { "subjects": [ "18B99", "35K10", "35K05", "35K55", "35K57", "58J70" ], "keywords": [ "second order parabolic equations", "partial differential equations", "nonlinear reaction-diffusion equation", "special cases", "special-purpose language" ], "note": { "typesetting": "TeX", "pages": 33, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2005math.....12094P" } } }
